Data Storage Management in Heterogeneous Memory Systems

Abstract

A data storage management system is provided, which includes multiple storage entities with differing storage characteristics. A controller is communicatively coupled to each of the multiple storage entities. The controller is configured to associate one or more storage attributes of a received object with one or more of the different storage characteristics, and to store the received object in one or more of the multiple storage entities based on the association of the one or more of the storage attributes of the received object with the one or more of the different storage characteristics.

Problems solved by technology

However, such methods may perform suitably when the parallelism has relatively equal capability and / or availability, but may not be optimal when capability and / or availability vary across the parallel channels.

Similarly, small transfers and metadata (which tends to be small) can emphasize the disadvantages of coupling such as lower packing efficiency, higher wear and higher power, and this system would use uncoupled accesses for small transfers.

Additionally, the illustrations are merely representational and may not be drawn to scale.
